      Malcolm,
      who are you talking to and what post are you referring
      to?
      You
      most certainly can shape internal gears with a single point
      tool.

      You can't produce internal gears....Wrong.. Polygon
      Solutions produce involute internal and external rotary
      broached gear forms.

            Malcolm, who are you talking to and what post are you referring to?

            You most certainly can shape internal gears with a single point tool.

              Hi Herb:

              It is a long long ways from a hex socket to an involute internal ring gear. 

              What is so very bad about shapers anyway? 

              I have been teaching people to make and use hex broaches for broaching hex sockets for years. Removal of the broach from the hole is easily accomplished by chucking the broach in a tailstock mounted drill chuck. Why would power be required for removal? 

              Again, how much would it cost for a rotary broach to produce an internal ring gear? I think you will find it to be more than the cost of a used shaper by a ways and the shaper can do much more than a single purpose rotary broach.

              Malcolm, who are you talking to and what post are you referring to?

              You most certainly can shape internal gears with a single point tool.

              You can't produce internal gears....Wrong.. Polygon Solutions produce involute internal and external rotary broached gear forms.

                    Hi
              Ian:
              Yes
              I am familiar with rotary broaching. You cannot produce
              internal ring gears with rotary broaching. What is the
              point?
              Thank
              you.

                  Otherwise how would you cut internal
              splines?    Bill in Boulder
